It's that time again: the software engineers at Samsung are on an open-source bender, and they won't stop until every last Galaxy phone has been served. Today Samsung posted kernel files for some big (as in widely-used) devices, and some not-so-big (but still actually pretty big) devices. Verizon's version of the Galaxy S4, the vanilla Galaxy Tab 3 7.0, the Galaxy Mega 5.8 Duos, and the GSM version of the Galaxy Mega 6.3 all have kernel source code posted at Samsung's open source repository.

Samsung just won't let anybody catch their breath when it comes to hardware releases. Just a few weeks after the worldwide release of the Galaxy S4, the company has posted public information for a new press event, explicitly declaring that new Galaxy and ATIV devices will be on display. Galaxy is of course Samsung's everything, everywhere brand for Android, and for those not in the know, ATIV is their newer generation of Windows products.

If you saw the Aurora Red version of the omnipresent Samsung Galaxy S4 yesterday and decided you just had to have it, AT&T has got you covered. Just let your fingers do the walking to the AT&T web store and get a pre-order in, and it'll be on its way in a little over two weeks. At present the $200 16GB model ($639.99 off-contract) is the only one available in a hue that matches your ruby slippers.

Attention, Verizon-shackled Samsung fans (like me): the Galaxy S4 is available today. Like, right now - you could probably drive down to the Verizon store and it would just be sitting there, waiting for you to fondle its 1080p screen. If you want to take it home, it'll cost you $199.99 with a new or extended two-year contract. Still clinging to that unlimited data like the last slice of pizza in the frat house?

Cricket Wireless wants you to know that they'll have the Samsung Galaxy S4, just like the big boys. They just don't have it yet. In a press release issued today, Cricket revealed its own special version of the Galaxy S4 (which is exactly like all the other LTE Galaxy S4 models), and it will be available to customers in-store, online, and at authorized resellers on June 7th. The cost for Cricket's unsubsidized phone is a wallet-searing $599.99, but those who are short on green can put $54.99 down and pay it off over a couple of years.

In case you hadn't heard, Samsung is making a little extra effort to secure the Galaxy S4 via tougher software kernels, which aren't susceptible to some of the more common root methods from previous Galaxy models. But where there's a will, there's a way, and noted Android developer/modder Chainfire has found a way around the security on the stock kernel for the Galaxy S4 i9505 - that's the Qualcomm Snapdragon-powered LTE variant, and the model sold for AT&T and T-Mobile in the United States.

The ruggedized Galaxy S4 Active is real. It's been spotted on camera before, not to mention in various less dramatic leaks. The folks at MobileTechReview got their hands on one, and it looks pretty close to finished, assuming that they don't already have a production model. In the video below, you can see the tougher red chassis (probably water and dust-resistant to some degree) and physical navigation buttons, as previously featured on Samsung's Rugby models.

Since their announcement last month, we haven't heard too much about the Galaxy Mega 5.8 and 6.3 (barring rumors of a delayed release). That doesn't mean Samsung plans on breaking its pattern of timely (or early, depending on your perspective) kernel source code releases. Keeping with form, Samsung has released kernel source for the 6.3" Mega's I9205 (LTE) variant.

There's no sign of the Mega's I9200 version (or the Mega 5.8) just yet, but given Samsung's track record, we can expect it any time now.

Good morning, Galaxy S III users. Want to start off your week with a spiffy new software build? Then the folks at SamMobile are happy to oblige. They've got their hot hands on a leaked build of the Android 4.2.2 (JDQ39) update for the S III, packing the standard Jelly Bean 4.2 upgrades and more than a few features back-ported from the newer Galaxy S4. The flashable ROM posted to the site isn't exactly official - it's cobbled together from dumped files - but flashing it via Samsung's Odin software won't void your warranty.

Well hi-diddly ho there, aspiring app developer! Has the life of a recent CompSci grad got you down? Does the world of independent mobile app programming leave something to be desired in the area of, say, ostentatious sports cars and penthouse apartments? Samsung would like to help you out with their Smart App Challenge 2013. A cool $800,000 has been reserved for the makers of ten winning apps, with 200,000 American greenbacks going to the top entrant.
